Abstract: The present invention relates to a process for obtaining polyols from used frying oils as the starting ingredient and converting the polyols to polyurethane products. The process comprises few steps such as epoxidation process by reacting used frying oil with an acid, reacting the epoxidised used frying oil with a monohydric or polyhydric alcohol in the presence of a catalyst to form a polyols, mixing the polyols with an additive or additives and a blowing agent or blowing agents and mixing the blended polyol with an isocyanate to form a polyurethane product.

Abstract: The invention relates to a biodegradable functional fluid composition based on vegetable oil. This functional fluid suitable for lubricant, hydraulic and like fluid comprises palm olein and its by-product generated from fractionation of palm oil. The by-product is esterified by a hindered alcohol prior to blend together with palm olein and additive packages. The hydraulic fluid particularly suited for tropical climate with temperature ranging from 15-40° C.
